The role of glucagon-like peptide 1-receptor gene in type 2 diabetes
Diabetologia Praktyczna 2006;7(3):150-154.
Abstract
INTRODUCTION. The aim of the study was to search
for the association between Gly168Ser and
Leu260Phe amino acid variants of the glucagon-like
peptide 1 receptor gene and type 2 diabetes in
a Polish population.
METHODS. 462 patients with type 2 diabetes and 428 healthy volunteers were genotyped by restriction fragments length polymorphism method after amplification of examined genome fragment by polymerase chain reaction technique. The digestion products were separated and visualized by electrophoresis on agarose gel containing ethidium bromide. Statistical analysis involved chi-square test for genotype-phenotype association and logistic regression for association of phenotype with haplotypes.
RESULTS. Ser/Ser homozygotes frequency in diabetic patients group was significantly higher than in control group (15.7% vs. 9.8%, p = 0,03). Odds ratio of having type 2 diabetes in Ser/Ser carriers group versus other genotype carriers showed almost two fold risk increase associated with this genotype. Polymorphism in 260 amino acid position and haplotypes of the analyzed polymorphisms were not associated with type 2 diabetes.
CONCLUSIONS. The results of the study suggest that polymorphism Gly168Ser may be potentially a risk factor of the type 2 diabetes in Polish population. This observation should be evaluated in other ethnic groups.
